| 1. | Evidently one of the main distinguishing characteristics of photon is just its zest rest mass .
显然光子的一个主要区别于其它粒子的特征就在于它的静止质量为零。
|
| 2. | In these reactions , rest mass is not conserved , although ( as in any other reaction ) , mass - energy is conserved
在这些反应方面,静止质量不被转换,虽然(同在任何其它反应方面一样) ,质-能被转换。
|
| 3. | Fundamental particles have an intrinsic mass known as their rest mass ( those with zero rest mass are called massless )
基本粒子有个称为静止质量的内在质量（静止质量为零的粒子称为无质量粒子） 。
|
| 4. | For a compound particle , the constituents ' rest mass and also their kinetic energy of motion and potential energy of interactions contribute to the particle ' s total mass
对于复合粒子来说，每个组成粒子的静止质量、动能以及交互作用的位能，都会贡献到粒子的总质量。
|
| 5. | A hypothetical particle postulated to be the quantum of gravitational interaction and presumed to have an indefinitely long lifetime , zero electric charge , and zero rest mass
引力微子一种假想粒子，被假定为引力相互作用的量子，并被推测为具有无限长寿命、零电荷和零静止质量
|
| 6. | The standard model lets us calculate that nearly all the mass of protons and neutrons is from the kinetic energy of their constituent quarks and gluons ( the remainder is from the quarks ' rest mass )
从标准模型可以得知，质子与中子的质量几乎皆来自夸克与胶子的动能（其馀的质量则来自夸克的静止质量） 。
|
| 7. | The effects of contact potential differences ( cpd ) in the experiments for testing coulomb ' s inverse square law and detecting the photon rest mass based on the concentric metal spheres were discussed , and the ultimate restrictions on hte experimental sensitivities due to cpd were presented for static experiments and dynamic ones respectively
摘要分析基于同心导体球壳方法检验库仑反平方定律和光子静止质量的实验中接触势的影响，并分别给出了静态和动态实验中接触势对实验灵敏度的限制。
